Actually, my main opponent is exclusively guild and maily perdita.
But i fail to see what the relevance is by listing thsoe 3...
Neverborn - Lilith and co are fast for sure but its only lilith herself that Hans can't take out... Pandora is a pain but slow with the changes to incite and pacifiy. Shoot the sorrows! Zoraida is a mixed bag but IMO the weakest of the NB.
Ramos - I use him regularly. Hans even has a good shot at worrying ramos from outside the range of ramos only offensive spell. Yes, spiders are fast but again, not unkillable for him with 1 shot...
Perdita - Yes, she is nasty. Yes, her crew is killable with Hans.
I am not saying hans is uber. I am just saying pick the right targets and make sure you mention he has head shot from time to time and you can make him work well
